Reaction Steps

460 mg (purity 90%, 1.38 mmol) of 5-(difluoromethoxy)-4-iodo-2-methoxypyridine and 299 mg (1.65 mmol, 1.2 eq.) of 5-chloro-2-cyanophenylboronic acid in the presence of [1,1-bis(diphenylphosphino)ferrocene]palladium(II) chloride/dichloromethane monoadduct were reacted according to General Method 2A. The crude product was purified by flash chromatography (IR-50SI, petroleum ether/ethyl acetate 10-15%). Yield: 230 mg (purity 80%, 43% of theory)
